STEPS TO REPRODUCE 1. Put a Sticky Note widget on your panel 2. Write lots of things in it that would be extremely disruptive or saddening to lose 3. Right-click on an empty area of the panel > Show Panel Configuration 4. Clone panel > click on one of the big arrows to clone the panel there 5. Delete the new panel 6. Restart plasmashell 7. Click on the Sticky Note widget on the *original* panel OBSERVED RESULT The sticky note is empty! Fortunately I had a backup from a few days ago. However, this is still data loss, and if without that backup it would have been irretrievable data loss. EXPECTED RESULT The sticky note's text is still there. SOFTWARE/OS VERSIONS Operating System: KDE Linux 2025-08-21 KDE Plasma Version: 6.4.80 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.1 Kernel Version: 6.16.1-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics Memory: 16 GiB of RAM (14.9 GiB usable) Graphics Processor: AMD Radeon 780M Graphics ADDITIONAL INFORMATION Here's what happened: the cloned sticky note retained its config data, so it was pointing at a specific file in ~/.local/share/plasma_notes/ — the same file that the old sticky note is pointing at! When the cloned panel was deleted, the cloned Sticky Note widget deleted the underlying file that both Sticky Note widgets were using. This made it unavailable to the original panel too, but only after restarting plasmashell or the system. At that point, data loss has occurred.
Likely caused by https://invent.kde.org/plasma/kdeplasma-addons/-/commit/98b2cb809c3a4bf7ebd3b4a318a1aa88a465f0d5
Side note: it would be good to move the underlying file to the trash rather than deleting it.
Which would likely represent a fix for Bug 453673.
